## Note: ls -l prints the modified timestamp

## Preserve dates when stripping to an output file.
# RUN: yaml2obj %s -o %t.1.o
# RUN: touch -m -t 199705050555.55 %t.1.o
# RUN: llvm-strip -p %t.1.o -o %t-preserved.1.o
# RUN: ls -l %t-preserved.1.o | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# Check that the stripped output is in fact a valid object file.
# RUN: llvm-readobj %t-preserved.1.o

## Preserve dates available via objcopy interface as well.
# RUN: yaml2obj %s -o %t.2.o
# RUN: touch -m -t 199705050555.55 %t.2.o
# RUN: llvm-objcopy -p %t.2.o %t-preserved.2.o
# RUN: ls -l %t-preserved.2.o | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: llvm-readobj %t-preserved.2.o

## Preserve dates when stripping in place.
# RUN: yaml2obj %s -o %t.3.o
# RUN: touch -m -t 199705050555.55 %t.3.o
# RUN: llvm-strip -p %t.3.o
# RUN: ls -l %t.3.o | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: llvm-readobj %t.3.o

## Without -p set, don't preserve dates.
# RUN: yaml2obj %s -o %t.4.o
# RUN: touch -m -t 199705050555.55 %t.4.o
# RUN: llvm-strip %t.4.o
# RUN: ls -l %t.4.o | FileCheck %s --check-prefix=CHECK-NO-PRESERVE-MTIME
# RUN: llvm-readobj %t.4.o

## Preserve dates in archives.
# RUN: yaml2obj %s -o %t.5.o
# RUN: rm -f %t.a
# RUN: llvm-ar cr %t.a %t.5.o
# RUN: touch -m -t 199705050555.55 %t.a
# RUN: llvm-strip -p %t.a
# RUN: ls -l %t.a | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: llvm-readobj %t.a

## Preserve dates in split DWO files.
# RUN: cp %p/Inputs/dwarf.dwo %t-input.dwo
# RUN: touch -m -t 199705050555.55 %t-input.dwo
# RUN: llvm-objcopy -p --split-dwo=%t-dwo %t-input.dwo %t-nondwo
# RUN: ls -l %t-dwo | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: llvm-readobj %t-dwo
# RUN: ls -l %t-nondwo | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: llvm-readobj %t-nondwo

## --preserve-dates and -p are aliases.
# RUN: llvm-strip --preserve-dates %t.1.o -o %t-preserved.1.alias.o
# RUN: ls -l %t-preserved.1.alias.o | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: cmp %t-preserved.1.alias.o %t-preserved.1.o
# RUN: llvm-objcopy --preserve-dates %t.2.o %t-preserved.2.alias.o
# RUN: ls -l %t-preserved.2.alias.o | FileCheck %s --check-prefix=CHECK-PRESERVE-MTIME
# RUN: cmp %t-preserved.2.o %t-preserved.2.alias.o

# CHECK-PRESERVE-MTIME:        {{[[:space:]]1997}}
# CHECK-NO-PRESERVE-MTIME-NOT: {{[[:space:]]1997}}
